Hey! I noticed that when I go through water crossings, (or even when I splash a big puddle), the cab fan will start ticking.

The sound is like a relay pulling in. The truck loses power instantly and if I don't turn the fan off, the truck will just die completely.

I'm guessing water is getting in to the fan motor, but I'm not sure how. Anyone have any ideas?

My other question, where can I source a primer for a 3b? I'm in canada, but it doesn't really matter where.
